signal isolation with Broadcom ACPL-224-560E dual channel phototransistor optocoupler in SO package
Product Overview
The Broadcom ACPL-2x4 series comprises AC-input, multi-channel, half-pitch phototransistor optocouplers designed for reliable signal transmission between circuits of different potentials and impedances. The ACPL-224 offers dual-channel isolation in an 8-pin SO package, while the ACPL-244 provides quad-channel isolation in a 16-pin SO package. Both devices feature high input-output isolation voltage (3750 VRMS), a typical response time of 2 s, and a minimum Current Transfer Ratio (CTR) of 20% at 1 mA input current. These optocouplers are suitable for applications such as I/O interfaces for programmable controllers and computers, sequence controllers, system appliances, and measuring instruments.
